Copper Sulfide an overview ScienceDirect Topics

All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a alytic manner in these reactions (shown for elevatedtemperature reaction conditions where the sulfurcontaining product is sulfate, rather than the elemental

CHALCOPYRITE (Copper Iron Sulfide)

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool''s Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.

Copper Mining and Extraction: Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.
